AUBURN, Neb. (AP) — A woman who pulled her 3-year-old grandson from a pond in southeast Nebraska says he wandered off while she was doing farm chores.

Authorities say Wayne Brown died Tuesday in an Auburn hospital after attempts to resuscitate him failed.

Wendy Presley said Wayne and his mother were moving in Tuesday to stay with her at her rural home southwest of Auburn. Presley says she told Wayne to go back to the house for lunch while she ground some corn and saw him head that way.

When she went to the house he wasn’t there, so she began searching and found him in the pond.

Presley told the station she tried to revive the boy and said his death “is a tragic, horrible accident.”
